London, United Kingdom
The relatively small area known as the City of London coincides with the ancient walled Roman city of Londinium on the north bank of the river (the line of the wall is marked closely for almost its entire length by modern streets), and includes St. Paul's Cathedral near where the Roman temple stood. For scale, the river is 265 meters wide near St. Paul's. The City is the financial center while Westminster is the center of government, including the Houses of Parliament and 10 Downing Street, where the British Prime Minister lives.
Several large structures visible in this image are railroad stations: three serving areas north of London (Euston, St. Pancras, and King's Cross), and Waterloo Station serving southern Britain. The London Eye, a famous Ferris wheel 140 meters high, is situated on an oval island in the River Thames, visible just west of Waterloo Station. Many larger buildings can also be identified, partly because they cast shadowsâ€” Buckingham Palace, St Paul's Cathedral, and the Tate Modern art museum (a converted power station whose 99-meter chimney was designed to fall just short of the crest of St Paul's dome).
